Question

Three randomly selected households are surveyed The numbers of people in the households are 2 6 and 7 Assume that samples of size n = 2 are randomly selected with replacement from the population of 2 6 and 7 Construct a probability distribution table that describes the sampling distribution of the proportion of even numbers when samples of sizes n = 2 are randomly selected Does the mean of the sample proportions equal the proportion of even numbers in the population? Do the sample proportions target the value of the population proportion? Does the sample proportion make a good estimator of the population proportion? Listed below are the nine possible samples. 2.2 2.6 2.7 G.2 6.6 6.7 7.2 7.6 7.7 Construct the probability distribution table Enter your answer in the edit fields and then click Check Answer.

Explanation / Answer

Here,

2 and 6 are even numbers. So, if we take the sample of n = 2 then proportion of even number can be 0, 0.5 and 1.

Hence,

The table would be:

Sample proportion Probability 0 1/9 0.5 4/9 1 4/9
